VaxStation 2000 PSU info needed

Is anbody intimate enough with the VaxStation 2000 to provide a couple of
details? Here's the deal:

I snagged a VaxStation 2000 box some time back, mainly for the PSU. It turns
out that it has a couple of lines, on the 9-pin MOLEX main power output
connector, the purpose of which is not clear. There's one that seems to float
at around -6 Volts DC, and another that floats at high-impedance, yet, when the
one at -6 is pulled to 0 (gnd) through a resistor, the previously floating one
suddenly has 9 volts or so. Do these have a specific purpose that might serve
some need I'm likely to encounter, or are they just for the DEC folks' features?
Is there any way to capitalize on them, or should I just leave them alone? All
I'm after is fairly normal power output, with the added benefit of a fan and
switch. The +5 and bipolar 12's seem to work fine. Spec's would be handy too,
e.g. how much current can be drawn from each of the supplies and, perhaps from
all of them at once?

Thanx,

Dick
